[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。  <:`x> _  
'FGf#l<  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： $:0?"?o);  
enableservice('AutomationServer', true) 
gz"I=9  
enableservice('AutomationServer') 0'^zIL#.  
b/'RJQSAc  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 C)0JcM

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： nsV;6^>  
1. 在FRED脚本编辑界面找到参考. pkEqd"G  
2. 找到Matlab Automation Server Type Library  .tRWL!  
3. 将名字改为MLAPP {@`Z`h"N

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 'B$qq[l]S

1. 创建Matlab服务器。 ]!04L}hy|P  
2. 移动探测面对于前一聚焦面的位置。 <Q?X'.  
3. 在探测面追迹光线 hKYA5]  
4. 在探测面计算照度 F;_L/8Ov1  
5. 使用PutWorkspaceData发送照度数据到Matlab X{bqG]j  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?3:xR_VWZu  
7. 用Matlab画出照度数据 -+=+W  
8. 在Matlab计算照度平均值 gdyP,zMD7  
9. 返回数据到FRED中 ^ G(GjW8
